A REAR BRAKE ANSWER???
 

Just reading in motorcycle news that Aprilia say that using DOT5 fluid in their rear brakes sorts the going soft problem.

Does it work on a Ducati?

Has anyone tried it?

Cheers Mike

I already use DOT5 and it still goes soft...

I think it's a general design fault in the way that the rear caliper is mounted in relation to the master cylinder and the run of the hose.

The SS has one really demon sharp rear brake and has never required bleeding, yet it uses the same system components. The difference is that the master cylinder is mounted vertically and not horizontally, and the caliper is mounted above the line of the m/c as it sits above the rear axle and not below.

I know the monsters use this configuration too, and also the 999/749 have gone back to mounting the rear caliper above the rear axle, but retain the horizontal master cylinder - do these suffer the same? If not, I'd be tempted to deduce it's just the location of the caliper.

I run DOT 6 and it isnt that bad. they stock it in the demon tweeks catalogue

never use the back brake...

...but then only go out on dry roads.

Or get your bike MOT'ed I presume?

Its approaching MOT time!!!!!

The only time it will ever get used:o

Mine got MOT'd at the weekend. Not so easy to sneak under the radar now with the new computer methodology.

My major worry was the back brake as it really is useless, but it did stop the rollers eventually with a good stamp and when the numbers were fed in to the computer it said PASS ! ! ! ! Mightily relieved!

Luckily don't have the MOT worry here on the Isle of Man :cool:

Has anyone used a mityvac? I did a search and there appears confusion over the instructions/units efficiency:puzzled:

Fit a 4 pston caliper to make it work at all.
